Embedded safety elevator

Abstract

An embedded safety elevator includes a van body, a motor, a battery, a driving wheel, a transmission rod, an embedded elevating device, and an inwardly concave spiral guide rail. The embedded elevating device is embedded in the guide rail and can move up and down along the guide rail; the embedded elevating device is fixed on the van body to drive the van body to move up and down, the motor and the battery are mounted on the van body and are connected with the driving wheel, the driving wheel is connected with the transmission rod, and the transmission rod is further connected with the embedded elevating device. The motor is started to drive the driving wheel to rotate, the driving wheel drives the transmission rod to rotate, the transmission rod transmits the power to the embedded elevating device for driving the embedded elevating device to spirally elevate.

CROSS REFERENCE OF RELATED APPLICATION[0001]This is a U.S. National Stage under 35 U.S.C 371 of the International Application PCT / CN2014 / 079309, filed Jun. 5, 2014, which claims priority under 35 U.S.C. 119(a-d) to CN 201310221810.5, filed Jun. 6, 2013.BACKGROUND OF THE PRESENT INVENTION[0002]1. Field of Invention[0003]The present invention relates to an embedded safety elevator, and more particularly to a spiral elevator which is capable of being embedded in the vertical track.[0004]2. Description of Related Arts[0005]Currently, there are three kinds of vertical and slope lifting elevators in the world: elevators hauled by counterweight steel wire ropes, rolling elevators and hydraulically vertical elevators. At present, elevators hauled by steel wire ropes are widely used at home and abroad, which are convenient for installation and maintenance and adapted for carrying passengers and cargoes in a building. However, elevators hauled by steel wire ropes are not adapted for currently...

AI Technical Summary

Benefits of technology

The present invention provides an embedded safety elevator that has a stable structure, is safe and reliable, does not occupy extra space, and is easy to install and use. Additionally, the elevator can improve operating efficiency, increase security, and carry capacity. It has a simple structure, is convenient for installation and operation, and can significantly reduce manufacturing costs.

Problems solved by technology

However, elevators hauled by steel wire ropes are not adapted for currently personal residential elevators.

However, the commonly household power supply systems are unable to load.

Furthermore, during operating process, elevators hauled by steel wire ropes have a certain degree of security risk, so that there is need for regular maintenance, thereby leading to high maintenance cost.

However, while the power is off, the brake is relieved, due to lack of the drive of the controllable power, the descent speed is not easy to be controlled, the van body of the elevator is not easy to be positioned at the normal opening position, it is difficult for passengers to normally open the door by themselves to leave the van body of the elevator.

If the motor is out of operation or deadlocked, the above design is unable to have an effect.

However, the spiral support has high manufacturing and installation cost and is not adapted for higher building elevators.

The elevator is unable to ensure the balance while operating and is easy to shake; which not only brings a certain degree of panic to passengers, but also leads to falling off of elevator parts after prolonged shaking, thereby resulting in damage of the elevator or more serious accidents.
